Driver Assistance Systems Front Camera, Calibrating: Procedure
As an example, the procedure is described for the Wheel Alignment Computer :VAS 701 001 .
- Note the test requirements. Refer to TEST REQUIREMENTS .
- Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .
-- Check if the Setting Device Basic Set :VAS 6430 is in the center position and is locked.
-- Check if the Driver Assistance Systems Front Camera -R242- fits correctly in the bracket and the viewing range for the camera is not blocked.
-- Vehicle with rear axle steering: drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.
-- Steer the rear axle to the zero position. Refer to REAR AXLE STEERING .
- This is the only way to ensure that the rear axle steering is in the straight-ahead position.
-- Vehicle with air suspension: adjust to standard vehicle height and lock. Refer to AIR SUSPENSION .
-- Check the DTC memory for the Driver Assistance Systems Front Camera - R242-. Fix all displayed entries.
-- Move the wheels so that they are straight.
-- Install quick-action clamps on the wheels.
-- Attach the reflectors to the quick-action clamps.
-- Perform the wheel run-out compensation.
-- Select the button for the driver assistance systems front camera calibration procedure in the wheel alignment computer.
- The ACC Setting Device must not be moved on the calibration beam.
-- Make sure the calibration board is positioned in the center and is locked in place.
- Dimension -a- = dimension -b-.
-- Position the Setting Device Basic Set :VAS 6430/1A at a distance of -a- 150 cm ± 2.5 cm from the center of the wheel hub on the front wheels to the beam on the Setting Device - Basic Set :VAS 6430/1A .
- Measuring tape
-- Place the Camera :VAS 701 001/1 -1- for the ACC adjustment on the Setting Device - Basic Set :VAS 6430 on the right side and tighten.
- For the next step, the alignment rack must be at the lowest level position.
-- Enter the height value -A- between the Setting Device - Basic Set :VAS 6430/1A contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.
- Height of the calibration board: 1, 400 mm + height value -A-.
-- Loosen the bolt -arrow- and place the measuring bar -1- on the floor.
-- Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.
TIP:
If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.
- If in later procedures the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.
-- Balance the bubble level -A- using the adjusting screw -1-.
TIP:
The bubble level adjustment -A- serves to balance the ground conditions.
-- Slide the Setting Device Basic Set :VAS 6430 to the side -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- Secure the Setting Device - Basic Set :VAS 6430 to prevent it from rolling by lightly tightening the screws -2- and -3-.
-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.
-- Balance the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
- Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked again. Refer to DRIVER ASSISTANCE SYSTEMS FRONT CAMERA, CALIBRATING .
-- Connect the Vehicle Diagnostic Tester.
-- Switch the ignition on.
-- Select and start the Diagnostic operating mode.
-- Select the Test plan tab.
-- Select the Select individual test button and select the following tree structure consecutively:

Continuation for all vehicles
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
Next, determine the height of the body.
-- Determine the height of the vehicle body -a- at all four wheels in the center of the wheel between the wheel contact surface and the lower edge of the fender or wheel housing.
